Excavation & Earthworks Beaumont Hills

It depends on the volume of material, the ground (shale over clay on undulating ground), access for the machine and how far spoil has to be carted. Every job gets a written quote after a site look, with the dig, cartage and cleanup spelled out, so you know what’s included before anything starts.

Usually, if the excavation is part of a build. Cut and fill beyond set limits, work near boundaries and anything on a lot with a flood, bushfire or heritage overlay needs approval as part of the DA or CDC. We work to the approved plans; check with your certifier before the dig is booked.

A trench, pool dig or single pad is a day or two; a knock-down site cut or a basement runs longer and depends on volume, ground and weather. Dates come with the quote, not after.

Not usually on the ridge blocks. Shale over clay on undulating ground, engineered fill on the estate. Blue-grey shale is ripped rather than broken; the sandstone is in the gullies and north toward Dural, not under the estate streets.

The block is benched: cut into two or three levels to the engineer’s plan, with retaining walls where the levels meet, so the new house sits on a flat pad instead of on fill. Cut and fill on slopes is regulated, so it goes through the approval with the retaining design.

Yes, and it’s the standard Hills pool. The shell sits on a bench cut into the hillside, with a cut for the retaining wall on the uphill side and the downhill side formed. The pool builder’s engineer decides the bench, and the site look decides the machine.

Reactive clay. It swells in wet winters and shrinks in dry summers, and anything poured on loose or uncompacted fill moves with it. A pad cut and filled in compacted layers to the engineer’s spec is what stops the new slab doing the same thing.

Yes. The old house down, slab and footings out, the block stripped and the new pad cut and compacted, as one run if you want the demolition handled too.
